Facebook is updating its Messenger iOS and Android app today with a couple of really interesting new features: the ability to record short voice messages, and a free calling service that utilizes users’ existing data plans but not their call allowance. Facebook noted on the app’s iTunes page that the calling service will roll out in the next few weeks, while the other features appear to be available to users today.

The new voice message feature will allow all users to record a voice message through a new record button (pictured above), but The Next Web explained Facebook is limiting the new VoIP calling feature to Canadian users initially. The app isn’t live on the U.S. store, but it has already landed in Canada and should be available everywhere soon.

To use the service, Canadian users will be able to log into their Messenger app, open a conversation with the person they want to call, hit the ‘i’ button in the top-right corner and selecting ‘Free Call.’ To send and receive calls, users will need to have the latest version of the app that is available today.
